Mabotolo a Torque-Shear a Giredi 10.9
Magawo Oyambira a Core
**Mafotokozedwe ndi Zipangizo:** Mafotokozedwe ofanana amayambira pa M16 mpaka M30, ndipo kutalika kwake nthawi zambiri kumayambira pa 40mm mpaka 220mm. Zipangizo zomwe zimagwiritsidwa ntchito zimaphatikizapo zitsulo za alloy monga 20MnTiB ndi 35VB. Mafotokozedwe a M16-M24 nthawi zambiri amagwiritsa ntchito 20MnTiB, pomwe mafotokozedwe a M27-M30 nthawi zambiri amagwiritsa ntchito 35VB. Zipangizozi zimapereka maziko a mphamvu yayikulu ya mabolts.
**Miyezo:** Iyenera kutsatira muyezo wa GB/T3632-2008. Mutu wa bolt udzalembedwa ndi giredi ya magwiridwe antchito ya 10.9S, pomwe "S" ikuyimira bolt yamphamvu kwambiri ya zomangamanga zachitsulo, zomwe zimathandiza kuzindikira ndi kutsata bwino.
Kapangidwe ka Mawiri Olumikizira: Mawiri aliwonse olumikizira amakhala ndi boluti imodzi, nati imodzi yamphamvu kwambiri ya 10H, ndi chotsukira champhamvu cha HRC35-45 chimodzi. Zigawo zonse zitatu ziyenera kupangidwa mu gulu lomwelo kuti zipewe kusintha kwa ma batch kusokoneza kukhazikika kwa kulumikizana.
Zizindikiro Zofunikira za Magwiridwe Antchito
Kapangidwe Kabwino Kwambiri ka Makina: Monga bolt yamphamvu kwambiri, mphamvu yake yolimba ndi pakati pa 1040-1240 MPa, mphamvu yake yotulutsa si yochepera 940 MPa, kutalika kwake si kochepera 10%, ndipo kuchuluka kwake kocheperako kumafika 42%. Imatha kupirira mosavuta katundu wosinthika komanso katundu wambiri woyambirira, imawonetsa kukana kutopa kwambiri, ndipo imatha kuchepetsa bwino kuchuluka kwa kupsinjika pansi pa katundu wosinthika, ndikuwonjezera moyo wa ntchito ya zomangamanga zachitsulo.
Kukana Kudzimbirika Kosinthasintha: Pali njira zosiyanasiyana zochizira pamwamba. Pa malo achikhalidwe, kufinya ndi kupopera ndi njira zina, zomwe zimapangitsa kuti pakhale filimu yoteteza yomwe imateteza dzimbiri komanso kukhazikika kwa coefficient ya friction. Pa malo apadera monga nsanja zam'madzi ndi malo okhala ndi mchere wambiri, Dacromet coating kapena hot-dip galvanizing ingagwiritsidwe ntchito. Dacromet coating, monga coating yochokera ku zinc-aluminium, imakhala ndi kukana kwambiri dzimbiri.
Ubwino wa Kapangidwe ndi Kapangidwe
Kapangidwe Kapadera: Mutu wa bolt uli ngati bowa ndipo kumapeto kwake kuli ngati sprite. Nsonga yonga sprite iyi ndi yofunika kwambiri pa kapangidwe kake komanso kuyang'anira ubwino wake. Pansi pa mutuwo pali chophimba choletsa kutsetsereka kuti bolt isagwe kapena kuzungulira panthawi yoyika, zomwe zimachepetsa mavuto achitetezo omwe amabwera chifukwa cha kuyika kosayenera.
Kukhazikitsa Kosavuta Komanso Kogwira Mtima: Kukhazikitsa kumagwiritsa ntchito wrench yapadera ya torque. Chikwama chakunja chimayikidwa motsutsana ndi nati, ndipo chikwama chamkati chimalumikizidwa ndi nsonga yonga ya sprite. Kulimbitsa kumachitika kudzera mu mphamvu yotsutsana. Torque ikafika pamtengo wokhazikika, nsonga yonga ya sprite imasweka yokha, kusonyeza kuti kuyika koyamba kwafika pa 95-105% ya mtengo wopangidwira. Izi zimachotsa kufunikira kwa kuyeza torque pamanja ndikupewa zolakwika zomwe zimachitika chifukwa cha kusinthasintha kwa coefficient ya friction mu njira zachikhalidwe za torque, zomwe zimapangitsa kuti kapangidwe kake kakhale kosavuta komanso kosinthika.
Madera Akuluakulu Ogwiritsira Ntchito
Bolodi iyi ndi gawo lofunika kwambiri pakugwirizanitsa kapangidwe ka chitsulo ndipo imagwiritsidwa ntchito m'njira zosiyanasiyana. Pa ntchito yomanga, ndi yoyenera machubu apakati a nyumba zazitali, ma trus a mabwalo akuluakulu, ma braid-column joints a mafakitale, ndi zina zotero; mu uinjiniya wa mlatho, ingagwiritsidwe ntchito polumikiza main beam, kulumikizana kwa mlatho ndi ma suspension bridge tower joints; kuphatikiza apo, ingagwiritsidwenso ntchito pazida zolemera monga ma tower crane ndi ma wind turbine towers, komanso ma steel structure connections m'malo apadera monga ma platforms a m'mphepete mwa nyanja ndi ma transmission towers, ndipo imagwirizana ndi mitundu yosiyanasiyana yolumikizira monga mtundu wa friction ndi mtundu wa pressure kuti ikwaniritse zofunikira zosiyanasiyana za stress.
